RESILIENT WHEEL.

Specification of Letters Patent.

Patented July 22, 1913.

Application filed September 18, 1912. Serial No. 721,071.

To all whom it may concern.

Be it known that l, Gannon E. Sraacnn, a citizen of the United States,residing at lVe-st End, in the county of Saline and State of Illinois,have invented certain new and usefulImprovements in Resilient lVheels;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will. enable others skilled intheart to which it appertains to make and use the same, reference beinghad. to the accompanying drawings, and to the letters and figures ofreference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in resilientwheels and comprises a simple and e'l'licient device of this naturehaving various details of construc tion and combinations andarrangements of parts which will be hereinafter fully described, shownin the accompanying drawings and then specifically delined in theappended claims.

I illustrate my invention in the accompanying drawings, in which Figurel is a side elevation of a resilient wheel made in accordance with myinvention. Fig. 2 is a detail sectional view on line 2-2 of Fig. 1. Fig.3 is a section on line 33 of Fig. 1, and Fig. l is a section on linel-4l of Fig. 1.

Reference now being had to the details of the drawings by letter, Adesignates the hub of a wheel which may be provided with any suitableroller or ball-bearings as may be desired for the reception of an axle,and flanges B arranged in pairs and spaced apart project from said axleand carry pivotal pins C, and other flanges l) radiate from the centralportion of the axle and are spaced apart and carry pivotal pins l). Thefelly of the wheel is designated by letter E and may be of any approvedform. In the drawings, the telly is shown as having circumferentialgrooves E, and E designates a tire, the marginal edges of which are heldin said grooves by means of the plate E which frictionally engages thetire and is held by means of the bolts l1 passing throu h. registeringapertures in said plate and telly, the bolts being retained by nuts EThe spokes of the wheel are made up of resilient rods F arranged inpairs, each pair of spokes being made of a single rod and in diagonalrelation with each other in order to securely brace the wheel. Each rodis bent upon itself to form loops i which are fastened to pivotal pins Ccarried by the flanges B and said rod is bent to form coils F througheach of which an arm F passes and which terminates in a hook F. Theportions of the rods which form said coils extend through a coiledspring G over which the ends of the hooks F engage. Said rod, after thetwo portions thereof pass through the coil G is bent to form a loop Gwhich is connected to a swiveled head H of the bolt H, which latter hasa squared portion. Said bolt ll has a threaded shank which engages a nutI which is mounted in an angular outlined opening in the wedgeshapedplate J which is seated in a similarly shaped. slot formed transverselyin the folly. it will be noted that the contact of the periphery of thenut with the wall of the angular-out]ined opening in the plate J willprevent the not from turning as the bolt is rotated. Nuts J are fittedto the threaded lugs upon said plate and tend to securely hold the samewithin the slot in the felly, while the marginal edge of the opening inthe plate serves to prevent the nut from ro tation. The various spokesare made similarly and constructed as shown and described.

In order to further reinforce and brace the wheel, rods N are provided,each of which is bent upon itself to form a loop N for engagement withthe pins D and each rod N has hooks 0 formed at its ends which engageover one end of the coiled spring Q and a rod R is bent upon itself atits longitudinal center and is pivotally connected to a swivcled head 3upon a bolt 'l which is fastened to the folly in the same manner asbefore described of the bolts connecting the outer ends of the spokes.The ends of the rod R have hooks R which engage over one end of a coiledspring through which the rod it passes.

By the provision of a resilient wheel made in accordance with myinvention, it will be noted that the spokes with the resilient coilmounted as shown and described will serve to take up the vibrationincident to a re hicle equipped with wheels passing over a rough roadand, by reason of the arrange ment of the spokes with portions at'anglesto each other, the wheel will be thoroughly braced. lo the event of itbeing desired to adjust the tension of the spokes, it may be done byturning the bolts which has swiveled connections with the nuts in thetelly, thus affording means tor keeping the spokes at all times taut.

hat I claim to be new is 1. A. resilient wheel comprising a hub havingflanges thereon arranged in pairs and spaced apart, pivotal pinsfastened to said flanges, a telly, bolts carried by the telly and havingswiveled heads, plates seated in the tellies and provided with openings,nuts mounted in said openings and engaged by said bolts, resilientspokes, each made up of a single rod which is bent at differentlocations to form loops engaging said pivotal pins upon the flanges,each rod bent to torm coils which are disposed at inclinations to eachother and each arm ot the rod passing through a coil and terminating ina hook, a coiled spring over which said hooked ends engage, said rodpassing through the coil engaged by said hooks and bent to form a loophaving connection with the swiveled head of the bolt, as set forth.

2. A resilient wheel comprising a hub having flanges thereon arranged inpairs and spaced apart, pivotal pins tastened to said flanges, a telly,angled slots therein, bolts carried by the telly and having swiveledheads, wedge-shaped plates seated in said angled slots in the telly andprovided with an opening, a nut seated in said opening and preventedthereby trom rotation, resilient spokes, each made up ot a single rodwhich is bent at different locations to torm loops engaging said pivotalpins upon the flanges, each rod bent to torm coils which are disposed atinclinations to each other and each arm ot the rod passing through acoil and terminating in a hook, a coiled spring over which said hookedends engage, said rod passing through the coil engaged by said hooks andbent to torm a loop having connection with the swiveled head of thebolt, as set torth.

3. A resilient wheel comprising a hub having flanges thereon arranged inpairs and spaced apart, pivotal pins fastened to said flanges, a telly,angled slots therein, bolts carried by the telly and having swiveledheads, wedgeshaped plates seated in said angled slots in the telly andprovided with an opening, a nut seated in said opening and preventedthereby troln rotation, integral threaded lugs upon said plate, nutsfitted thereon to hold the plate in place, resilient spokes, each madeup of a single rod which is bent at different locations to form loopsengaging said pivotal pins upon the flanges, each rod bent to torm coilswhich are disposed at inclinations toeach other and each arm ot the rodpassing through a coil and terminating in a hook, a coiled spring overwhich said hooked ends engage, said rod passing through the coil engagedby said hooks and bent to form a loop having connection with theswiveled head ot the bolt,

as set torth.

4. A resilient wheel comprising a hub having flanges thereon arranged inpairs and spaced apart, pivotal pins fastened to said flanges, a telly,bolts carried by the telly and having swiveled heads, plates seated inthe tellies and provided with openings, nuts mounted in said openingsand engaged by said bolts, resilient spokes, each made up ot a singlerod which is bent at different locations to term loops engaging saidpivotal pins upon the flanges, each rod bent to torm coils which aredisposed at inclinations to each other and each arm ot the rod passingthrough a coil and terminating in a hook, a coiled spring over whichsaid hooked ends engage, said rod passing through the coil engaged bysaid hooks and bent to-tor1n a loop having connection with the swiveledhead of the bolt, rods bent upon itselt to term loops and positionedintermediate the resilient spokes and terminating at their ends inhooks, one of said intermediate rods pivotally connected to the hub andthe other to the telly, and a coiled spring engaged by the hooks uponsaid intermediate rods, as set torth.

In testimony whereot I hereunto aflix my signature in the presence ottwo witnesses.
